Wat Thung Si Muang (วัดทุ่งศรีเมือง) is located on Luang Road in Ubon Ratchathani. The temple was built by Venerable Chao Khun Phra Ariyawongsachan around 1829 during the reign of King Rama III and has a beautiful Ubosot (Ordination Hall) in the northeastern architectural style that is very tall in relation to its width. Venerable Chao Khun Phra Ariyawongsachan brought a replica of the Holy Footprint from Wat Srageath and a hall was constructed to house the replica. The hall was transformed into the Ubosot (main chapel or Ordination Hall) in 1829 by Ykhuchang, a monk from Vientiane who was expert in construction work. The art form of the Ubosot is, therefore, a mixture of the early Rattanakosin and Lan Chang styles. The lower structure of the Ubosot is in the northeastern style and the roof is of the Rattanakosin art form. A scripture hall or library (called a mondop in Thai) named Ho Phra Traipidok or Ho Trai Klang Nam is located in the middle of a pond, and features a roof that shows the Burmese architectural style while the lintel is carved in Laotian architectural art. Mural paintings in the temple feature the civilizations and cultures of the people of Ubon Ratchathani over 200 years ago
